5-Wheel Take Up Mechanism in Jute Weaving

Last Updated on 29/03/2021

Experiment name:
Study on 5-wheel take up mechanism (jute).

Take-up is to draw a fabric to the cloth roller regularly as it is woven. Texture of a fabric largely depends upon the number of ends and picks per centimeter or inch. This motion determines the number of picks of weft per inch or centimeter and contributes to the uniform texture of the fabric. It is the work of the weaver for accurately fixing the position of the fell of the cloth before starting a loom.


  1. To know about the construction of the mechanism.
  2. To know about drive of the take-up motion in jute weaving.

Take up motion:
The process of withdrawing fabric from weaving zone at a constant rate and then winding the woven cloth on the cloth roller with the continuous progress of weaving is called take up motion. It is a secondary motion of weaving machine.


(1) According to drive:

  1. Positive take up.
  2. Negative take up.

(2) According to motion of the cloth/Rate of take up:

  1. Continuous
  2. Intermittent

(3) According to drive given to the cloth roller:

  1. Direct drive
  2. Indirect drive

(4) According to number of gear train:

  1. 5-Wheel
  2. 6-Wheel
  3. 7-Wheel

(5) According to brand name:

  1. Sulzer
  2. Pickanol
  3. Toyota


  1. Ratchet Wheel (54)
  2. Change Wheel (44)
  3. Stud/Compound (70)
  4. Stud/Compound pinion (27)
  5. Take up Wheel (8/2)
  6. Take up Roller Dia (10.5inch)
  7. Cloth Roller
  8. Pushing Paul
  9. Holding Paul

A – Beam wheel

E – Ratchet wheel
F – Change pinion
G – Pushing pawl
H – Catcher
I – Fulcrum
J – Finger

It consists of a train of five wheels. Of these five wheels ratchet, stud and cloth roller wheels are driven wheels while change and stud pinions are driver wheels. The motion is primarily imparted from the sley sword. The sley sword is connected to the sley that gets motion from crank shaft and the crank shaft gets motion from motor by gearing. At the bottom of sleysword a connecting rod is connected which passes the motion to the monkey tail. The monkey tail is fulcrumed with two pawls: the upper is holding pawl and lower is pushing pawl.

These two pawls are mounted freely to the ratchet wheel which is the 1st wheel of this mechanism. The ratchet wheel is connected with the change pinion by shaft which is the 2nd wheel. Under the change pinion the 3rd wheel named stud wheel is geared. This wheel is geared with the stud pinion, the 4th wheel. The 5th wheel is take-up roller wheel which is geared upon the stud pinion.

The cylinder upon which the woven fabric is wound, is connected with this wheel by shaft. Now when the sley moves one time after one pick insertion the connecting rod pass this motion to the monkey tail and as the pawls are fulcrum with monkey tail they get upward motion. Using this upward motion the pushing pawl pushes the ratchet wheel one time and the holding pawl holds the ratchet in this position. Finally the cloth roller gets the motion by gear train and thus fabric is wound on cloth roller continuously with the weaving of fabric.

The take-up may be grown or lessen by changing the position of monkey tail and pawls where they are slotted. The more the distance is between them the more take-up is occurred and vice versa.

By this experiment we know about how to cloth is collected by 5-wheel take up mechanism. This is an interesting experiment too. We hope this will be very helpful in our practical life.
